Description

Gets a variable's value via a "value container". This container lets you fetch the variable's value in its native form, rather than being forced into a string (see GetVariableStringValueByName()). The variable's value is returned from the container via any of its GetValue*() methods, like GetValueFloat().

Returns true if a variable with the provided name exists, else false. If the variable does not exist, the value container will be initialized to an empty one, which defaults to containing a float with value 0. The evaluated graph does not store a reference to this value container, so if used outside of blueprints, be sure to keep a reference to it in order to prevent it from being garbage collected.
